Although significant advances have been made in the understanding of varicoceles, a clear pathophysiologic mechanism remains elusive. Most likely, a varicocele is the result of a multifactorial process. Appreciation of the complex venous drainage of the testis remains a key to maximizing the chances for treatment success. Likewise, the advent of microsurgical repair has minimized complications. Fortunately, times have improved since the early nineteenth century, when the French surgeon Delpech (1772-1832) was killed by a disgruntled patient on whom he had performed a varicocele repair.

Purpose: This study investigated the long-term efficacy of n-butyl-2-cyanoacrylate-metacryloxysulpholane (NBCA-MS) for varicocele embolization (VE) without using a microcatheter.
Methods: A retrospective study was conducted on male patients who underwent VE with NBCA-MS for grade III-IV varicocele between January 2016 and December 2022. Patients were categorized by the catheter type used.

Varicoceles are a common contributor to male infertility, significantly impacting male-factor infertility cases. Traditional diagnostic methods often lack the sensitivity to detect the molecular and cellular disruptions caused by varicoceles, limiting the development of effective, personalized treatments. This narrative review aims to explore the advancements in proteomics and metabolomics as innovative, non-invasive diagnostic tools for varicocele-associated male infertility and their potential in guiding personalized therapeutic strategies.

Article Synopsis
- Varicocele affects up to 15% of men and is linked to infertility; various surgical and radiological methods exist for treatment, but their effectiveness is uncertain.
- A study comparing the Ivanissevich surgical technique and sclerotherapy in 94 patients found that sclerotherapy significantly improved sperm concentration, while surgical treatment reduced the number of patients with oligozoospermia.
- Overall, the study did not determine a clear advantage of one method over the other but highlighted the importance of considering sperm bio-functional parameters in future research.
Enhancing Male Fertility Through AI-Based Management of Varicoceles.

Review Purpose: The clinical management of subclinical and symptomatic varicoceles in male infertility remains challenging. Current guidelines focus on treating men with abnormal semen analyses, but a more precise approach to identify, stratify, and prognosticate men with varicoceles and fertility issues is essential.
Recent Findings: Multiple studies have utilized Artificial Intelligence (AI) to analyze clinical-demographic characteristics, semen analyses, pre-operative imaging findings, and intra-operative clinical data.
Varicocele (VC) is widely recognized as a prevalent etiological factor contributing to male infertility. It has been established that the generation of reactive oxygen species (ROS) plays a significant role in the progression and development of VC. Antioxidants may regulate ROS levels in these patients.
